* To better comply with the GFDL license, the source DocBook XML files together with the plain text copy of the GFDL license and appropriate legal notice are now distributed in tarballs with each documentation release, and the exact way of how to obtain the source files is mentioned explicitly in the document; thanks to Ricardo Mones for pointing these legal issues out
